Snowbirds

Meet Junco hyemalis - one of the sweetest little birds to share the winter with us is the dark-eyed junco.  You're unlikely to confuse this species with another bird as this member of the sparrow family sports a slate-colored head and back, white belly and pink beak.  Quite distinctive.

These little birds migrate from Canada to winter here in tropical Wisconsin.  All I've ever observed are juncos of the male persuasion and I am told that females do not travel as far south as the boys do.   

They'll readily come to a feeder and it is not unusual to see a flock of them scratching-about on the ground.

They're commonly called Snowbirds.
